I&T in Tucson: Planning Develop integration plan Develop test plan Ensure appropriate knowledge transfer between SLAC & Telescope & Site

I&T in Tucson: Preparation Procure Lab Procure space in computer room Procure required utilities (comms, power, glycol) Test utilities Install DAQ in computer room Develop handling plan Develop power and grounding plan Develop safety plan Review safety, handling, power and ground plans Design handling & test fixtures Acquire/build handling & test fixtures Lab readiness review

Integration & Test Set-up SLAC equipment in lab Receive cryostat Unpack and setup cryostat in lab Post-shipment cryostat testing Integrate Cryostat with L1-L2, L3, Filter Changer, and Shutter Integrate filter changer controller with Utility Box Comprehensive test (scope?) Integrate ComCam and Utility Box with ComCam Integrating Structure (possibly in flex rig room)

Packing and Shipping Determine level of disassembly necessary Develop packing plan Develop shipping plan Procure packaging Disassemble Pack Ship
